The Gerontological Society of America (GSA) is the nation’s oldest and largest interdisciplinary organization devoted to research, education, and practice in the field of aging. The principal mission of the Society — and its 5,400+ members — is to advance the study of aging and disseminate information among scientists, decision makers, and the general public. GSA’s structure also includes a policy institute, the National Academy on an Aging Society, and an educational branch, the Association of Gerontology in Higher Education. Founded in 1945, GSA is the driving force behind the promotion of gerontology — both domestically and internationally. Its members come from over 40 countries. The organization fosters collaboration between biologists, health professionals, policymakers, and behavioral and social scientists. This stems from the belief that the intersection of research from diverse areas is the best way to achieve the greatest impact and promote healthy aging. Through networking and mentorship opportunities, GSA provides a professional “home” for career gerontologists and students at all levels.
